She wants tone

Neanderthals may have ruled your college campus, but in the real world, women prefer muscle tone over muscle mass, according to a new UCLA study. When 141 women evaluated photos of shirtless men, they ranked athletic-looking bodies (lean and defined) as more desirable than both muscular and skinny types. Study author David Frederick Ph.D.(c), says that women perceive men with big muscles as threatening and also know that it takes time to build all that beef - time you might not spend with them. "They're looking for signs of not only health and fitness but also a potential commitment," Frederick says.
